Software for Online O2, OUR, pH & Biomass monitoring in Shake Flasks

PreSens Flask Studio

The SFR vario is delivered with a basic software, which is the control center for the device. The connection between PC and the system inside the shaker is wireless. The software can control up to 4 SFR vario simultaneously. Oxygen, pH and biomass are visualized in real-time during the entire cultivation and running measurements can be compared with former ones. The measurement data can be exported in different file formats (e.g. Microsoft Excel®) for further analysis.

  • Enables process monitoring in shake flasks
  • Online optical biomass monitoring of microbial culture
  • Systematic optimization of cultivation parameters
